the flash EPROM
The application program instructions for your
PTC-960X are stored in an electronic component
inside the PTC called a flash EPROM. This is a

EPROMs, flash EPROMs can be erased and re-
programmed while they are inside the PTC. This
allows you to update your application program

application flash EPROM, you must connect
your PTC to an MS-DOS-based personal com-
puter and then run the FLASHPC.EXE utility to
download the special file (ROM image file) con-
